The door of the courtyard house has been welded dead

"You said this thing is an anti-aircraft machine gun?"

Looking at the two long parallel "gun" barrels in the unloaded box, Li Xuewen, who was squatting at the muzzle and indicating the caliber with his fingers, pulled out the three fingers inserted into the muzzle.

That’s right, the trumpet-shaped “gun” muzzle expands outward and can barely fit three fingers in. The tube body, which is as thick as a baby’s arm, can at least fit two fingers in.

Does this caliber have anything to do with the gun?

"65 double 37, this should be a cannon, a 37mm twin-mounted anti-aircraft gun~!"

Li Xuewu, with most of his body almost buried in the box, fished out a booklet from a corner. It looked like an instruction manual, but it contained the real name of the item.

"Did you send it to the wrong place? This thing shouldn't be in the air defense unit. We are in the capital, why do we need it?"

Erkui, who had been confused and excitedly talked about the anti-aircraft machine gun just now, now looked a little embarrassed. He scratched the back of his head, looked at one of the soldiers in charge of escorting, and asked him.

"Beijing Red Star Steel Rolling Mill, if the name on your wall is correct and the railway line is correct, then that is your factory~!"

The squad leader of the soldiers in charge of escorting the goods had a serious expression on his face and pointed to the concrete pillar next to the north gate. The factory name was painted red on it from top to bottom, and the letters were large and very clear to see.

The head of the security department, his younger brother, and the security officer looked at each other. Li Xuewen, who was squatting on the ground, stood up, wiped the gun oil on his fingers on the wooden frame, and greeted the people at the freight point.

"You guys unload first, I'll go talk to the deputy factory manager~!"

Looking at the weapons and ammunition piled up in the freight car that took up most of the car, Li Xuewen felt uneasy. The security department had no place to put the huge "heavy machine gun".

Gunner, gunner, the security department is the only place in charge of guns, but now they have sent cannons and rocket launchers. It doesn't look like a set of equipment for the security department at all. I don't know whether it is a good thing or a bad thing.

People came one after another to watch the fun. Not only the guard on duty at the north gate was curious, but even the unloading staff at the freight point all rushed to peek at the disassembled 37 twin-barreled anti-aircraft gun.

"If this thing hits someone, it will leave bruises all over the body. This muzzle, this barrel, tsk tsk?"

"I'm afraid it's not all bruises~!"

Li Xuewu muttered as he climbed onto the carriage and found the shells that were delivered along with the anti-aircraft gun.

Looking at the shells in the box that were almost as long as arms and two times thicker than a rolling pin, the length of the warhead alone exceeded that of the bullets of the high machine gun.

"37-55, 40-70-384, the ammunition looks old!"

I picked one up and shook it in my palm. The heavy weight gave me a very solid feeling.

Compared to the brand new anti-aircraft guns that smelled of gun oil, the ammunition in the box did look a bit old.

Looking at the number on the bullet body, Li Xuewu felt.

The 37 after the 55 may mean that it was produced in . As for the numbers below, they should be the manufacturer and production batch.

"Be careful, don't knock the primer. This whole car is full of ammunition. You can destroy the factory!"

Looking at Li Xuewu's dangerous moves, Erkui swallowed nervously.

Not only were my eyelids trembling, my heart was trembling as well, because there was a rocket launcher in the car.

Although he confused the machine gun with the anti-aircraft gun, it doesn't mean that he didn't know what a rocket launcher is.

"It's not that exaggerated. At most, the freight station was overturned~!"

Despite saying so, Li Xuewu still put the ammunition into the box and began to supervise the unloading workers in carrying the ammunition.

Two people were working, one on the truck and the other off, and there was no need for special instructions. When the unloading workers heard that they could overturn the freight station, their movements were unusually gentle.

"What do you mean, where to put it?"

Seeing his brother coming back from the North Gate Duty Room, and presumably having finished his phone call, Li Xuewu leaned against the side of the carriage and asked curiously.

The amount of ammunition in this half of the carriage, including anti-aircraft guns and rocket launchers, is enough to fight a small-scale positional battle and air defense battle. It is really generous.

"Put it in the detention room first, and move it away when there is room for it later~!"

Li Xuewen, the head of the Security Department, felt a tingling sensation in his back teeth. These things were temporarily stored in the Security Department.

Working in there is like sitting on a pile of gunpowder. The risk factor rises sharply.

"I guess it has something to do with the shooting range renovation?"

Li Xuewu, who had just been rejected from the shooting range, directly connected the two.

It was neither early nor late to change. As soon as the change was made, these high-powered weapons were delivered. It seemed like they were prepared in advance.

The earth wall, which is more than ten meters thick, is indeed vulnerable to this kind of weapon. Without cement and steel bars, who knows if it will accidentally penetrate through it.

"Then forget about it. I've never fought this thing before. It's good to try some meat!"

Patting the edge of the wooden box of the anti-aircraft gun, Li Xuewen looked at the boxes of unloaded shells and 56 rocket launchers and wiped his palms.

Li Xuewen has shot pistols, semi-automatic rifles, assault rifles, and heavy machine guns, but they are all guns.

I've never fired a cannon, no matter if it's an anti-aircraft gun or a rocket launcher, they're both more exciting than guns.

Since the shooting range renovation was prepared for these things, the security department should at least be able to personally fire a few shots to try it out, and he, as the section chief, must take the responsibility. The tricycles came and went one after another, until the last trip, after counting all the supplies, Li Xuewen, the section chief, signed the receipt.

"Stay for dinner before going back, or what's the plan?"

Looking at the soldier in charge of escorting the vehicle and handing back the signed form, Li Xuewen took the initiative to ask.

"He will stay here to instruct you on the installation and usage of weapons~!"

The squad leader pointed to one person, and then he and the escorting soldiers closed the door of the freight car, of course, from the inside.

With the train's front end turned around and reconnected, the train drove out of the north gate of the steel rolling mill.

At the same time, the Security Department was also in chaos.

Boxes of green-painted ammunition were moved from the truck to the detention room.

In the detention room, the petty thieves and hooligans who had been arrested were also transferred to the police station.

When they saw the arrival of the new weapons, both the security officer and the security guard reacted in the same way as the section chief did when they saw these things.

After the initial excitement wore off, they couldn't help but suck their teeth when they thought about their workplace, which was filled with explosives.

"It's time to eat. The things must be taken care of. The staff on duty should be more careful. If these things are lost, it will be much more powerful than a bayonet~!"

After giving instructions to the security department, Li Xuewen left in a hurry.

This is to go find someone.

Now he just wanted to ask Deputy Director Li what the Security Department needed these things for. These things would not be useful to thieves who climb over the wall.

Steel rolling mill laboratory.

Li Feng, the instigator, was here at this moment, staring at Ran Qilin with empty eyes, while dripping unknown liquid into a glass test tube.

Then a thick yellow smoke gushed out from the mouth of the test tube, looking like an evil wizard mixing some unknown poison.

He subconsciously distanced himself from the audience, as if he was talking to Ran Qilin who was doing the experiment, or as if he was talking to himself.

"Professor Ran, can our factory develop high-strength steel plates that don't require corrosion resistance, but are just hard!"

Ran Qilin, who was doing an experiment, was wearing a gas mask. Judging from the white rope hanging on his ear, he should be wearing a mask underneath.

Wearing rubber gloves on both hands, he used a test tube clamp to pick up the test tube that was no longer emitting smoke, and slowly placed it on the alcohol lamp to heat it.

He had no intention of paying any attention to Li Feng at all. He only took off his mask and gloves after the experiment was over and the distilled liquid was stored.

"How hard?"

After slowly wiping the table, washing the utensils, washing his hands and drying them, Ran Qilin looked at Li Feng and asked slowly.

"Of course the harder the better. It would be best if it could withstand the impact of bullets. If it hits you, it will just leave a dot or a little dent. It's all acceptable as long as it can't penetrate!"

Li Feng made a pistol shooting gesture and discussed with Ran Qilin the next possible research direction.

"Bulletproof steel plate?"

Ran Qilin's expression was calm, and he said what Li Feng wanted to say in just one word.

Li Feng smashed his palm with his fist and nodded vigorously. As expected, talking to a professional did not require much effort.

"A 1cm thick ordinary steel plate can protect against pistol bullets, right? A 2cm thick one should be able to protect against rifle bullets. There is no need to research it, the factory can make it ourselves~!"

Ran Qilin scratched his chin and gave a reasonable answer without much hesitation. If you want to make the existing steel plates bulletproof, you can easily do it by increasing the thickness.

It is already a piece of cake for a steel mill to use a rolling mill to roll out steel plates of suitable thickness.

"How could I not know that, Professor Ran? I also know that the thicker the better, but a person's ability to bear weight is not limited~!"

Li Feng smiled bitterly and spread his hands. If he could compete with the Space Marines, he would wear a 5-centimeter-thick tortoise shell all over his body, so that even the machine guns wouldn't be able to penetrate it.

"For use on humans?"

Ran Qilin looked at Li Feng meaningfully, then found a few pieces of steel plates that had been used before from the experimental cabinet, the kind that were not corrosion-resistant enough and had just enough strength, and placed them one by one on the experimental table.

"I want something that's roughly the right size to cover the main organs of the torso, with one piece on the front and one on the back. The weight should be no more than three kilograms, probably within this range~!"

After gesturing in front of his chest, Li Feng still didn't know which of the steel plates was light or heavy.

As the Party A, he is only responsible for making requirements and determining specific parameters. The rest is left to Ran Qilin to implement.

"At this weight, the thickness should only be able to protect against pistol bullets and fragments at most. As for rifles, I don't know because I haven't used them. The impact force of bullets is related to the caliber and charge~!"

He pulled over a scale, simply weighed a few test steel plates, calculated the area drawn by Li Feng, and after figuring out the approximate weight, Ran Qilin shook his head.

“What if we add ceramics?”

"Impossible, ceramics can't reach this strength~!" (End of this chapter)
